Very unlikely to get AC or DL due to their relationships with AMEX.
AC has got the business of BOFA, so obviously they don't care much.
Same is DL and AC have gotten business of Diners Club.
AS, EK, FB, and SQ are possibilities though. Any others I should bring up?
I believe any foreign airline would never stick to a specific bank etc, as we can see from BA, SQ, etc..
